The Atlantic Charter, agreed upon by Franklin D. Roosevelt and Winston Churchill in August 1941, was significant in shaping post-war peace by outlining shared goals for the world after World War II. The document emphasized principles such as self-determination, economic cooperation, and the disarmament of aggressor nations. It also laid the groundwork for the establishment of the United Nations, reflecting a commitment to multilateral cooperation and collective security. The values enshrined in the Atlantic Charter guided subsequent international agreements and institutions, promoting a vision of a more stable, just, and peaceful world order in the aftermath of the war.
